Neurology is a medical specialty dealing with disorders of the nervous system. Neurology deals with the diagnosis and treatment of all categories of conditions and disease involving the central and peripheral nervous system; or, the equivalent meaning, the autonomic nervous systems and the somatic nervous systems, including their coverings, blood vessels, and all effector tissue, such as muscle.
A neurologist is a physician specializing in neurology and trained to investigate, or diagnose and treat neurological disorders. Neurologists may also be involved in clinical research, and clinical trials, as well as basic research and translational research. While neurology is a non-surgical specialty, its corresponding surgical specialty is neurosurgery. Neurology, being a branch of medicine, differs from neuroscience, which is the scientific study of the nervous system in all of its aspects.
